Spring 3 jQuery Ajax删除

Question

I am trying to do ajax delete with jquery but getting http error 400. I was searching and I've seen that there is some problems with delete method in jquery.

Here's my js, controller(spring 3) and request from Chrome.

If you now what is the mistake please tell, or give some links.

$.ajax({  
                url: 'additions/cancelUpload',  
                type: 'DELETE',  
                data: {filename : ui.draggable.get(0).file.name},  
                success: function (res) {  
                    alert(res);
                }  
            }); 

execution does not passed here:

@RequestMapping(value = "cancelUpload", produces="text/html")
    @ResponseBody
    public String cancelUpload(@RequestParam("filename")String filename, HttpSession session ){ 
... 
} 

request:

I manage to recive request as DELETE

 @RequestMapping(value = "cancelUpload", produces="text/html" method = RequestMethod.DELETE)

but do this with

$.ajax({  
            url: 'additions/cancelUpload',  
            type: 'POST',  
            data: {filename : ui.draggable.get(0).file.name, _method: 'DELETE'},  
            success: function (res) {  
                alert(res);
            }  
        }); 

you can read about _method: 'DELETE' parameter of post request in http://blog.springsource.org/2009/03/08/rest-in-spring-3-mvc/
